摘　　要：传热学中很多问题归结为解微分方程和求出函数的积分,以几种典型的传热学方程为例,介绍了一种新的能直接求解的方法,即微分算子级数计算法(DSM)。为快速求解同类问题的精确解提供了一种新的工具。Many problems conclude to solve the differential equations and to compute the integrations of the functions in heat transfer. In the paper, a new method- differentiator series method (DSM) for three kinds of integration in heat transfer is introduced with some typical illustration of heat transfer equations. Thus, a new means were provided for the same kinds of problem.
